'SPECIFICATION forming part of Letters Patent No. 575,631, dated January19, 1897.

Application filed September 19, 1896. Serial No. 606,889. (No model.)Patentedin England May 28, 1894, No. 10,236.

'o LZ whom it may concer/t:

Be it known that LJOHN BOULTBEE BROOKS, manufacturer, trading as J. B.Brooks do Co., a subject of the Queen of Great Britain, residing atCriterion Vorks, GreatvOharles Street,

in the city of Birmingham, England, have invented certain new and usefulImprovements in Cycle-Saddle Attachment-Bosses, of which the followingis a specification, and for which 1o I have obtained Letters Patent ofGreat Britain, bearing date May 28, 1894., and nu rnbered 10,235.

This invention relates to detail improvements in attachment-bosses forsecuring cycle-saddles to their L pins or supports, and

has for one of its objects a universally-adjustable boss.

Figure 1 of the accompanying drawings represents a side elevation of auniversal boss 2o constructed according to one form of my invention andapplied to a wire saddle-supporting frame having single wires upon eachside. Fig. 2 represents a cross-section of the same, but with thedrawing-to bolt shown in elevation. Fig. 3 is an under side plan of theboss Fig. 1, showin g the dispositions of the rods of the double-sidedframing. Fig. 4 represents sections and elevations of the componentparts of the boss separately. Fig. 5 3o represents the said boss, Fig.1, applied to a four-wire framing or a framing in which each side hastwo wires. Fig. 6 represents a top side plan of my improvements appliedto a l pierced sheet-metal frame. Fig. 7 is a trans- 3 5 verse verticalsection of Fig. 6 with the drawing-up pin in elevation. Fig. 8 is a sideelevation of a part of the framing and the boss.

In Figs. 1 to el, a is a nearly-all-round clip 4o with the terminal andfree ends CL2, formed with lugs a3, having allthrough holes a4 throughthem, and with its outside faeings a being of soft metal.

h are washer-lugs, each having a circular hole b3 through it, akeep-groove b2 sunken within its inner face, and a rest-lug b upon itsupper inner part, which' seats within one of the two keep-grooves f f3,formed within the outer face of an interposed and rotating har- 5odened-steel washerf, having a circular hole f2 through its middle fortaking onto the round outerv part c2 of a screw-ended square spindle c,and teeth or serrations f4 upon its inner face. It will be observed thatthe said teeth run in directions at right angles to the direction of thekeep-grooves.

After the spindle chas been passed through the eyes a4 of the clip andthe components have been threadedV in the proper relative order upon theround end of the spindle, with 6o the frame Wire or rod member e lyingbetween the keep-grooves 192]@3 of the washers h and f, then by screwinghome the nuts d upon the screwed ends c2 of the spindle c the teeth f4are slightly embedded into the soft- 65 metal faces d of the clip a andslightly close the branches a2 thereof, while the frame-rods are drawncloser together and secured to the clip and the clip to the L orvertical seat-support in any desired position, hence a uni- 7o versalboss which admits of the saddle being tilted or adj usted, or of the eyeof the clip being directed in any position suitable for taking eitherupon an L-pin or a vertical Support.

In Fig. 5 the whole of the part-s of this form of boss are the same asthose of the one already deseribed, other than that double keepgroovesb2 b4 are formed in the outer washers, and the rest-lugs ZJ aredispensed with, so 8o that the wires e of the frame lie within theopposed keep-grooves of both the inside and outside Washers.

If necessary, the cross-pin instead of being square may be made roundand faceted upon 8 5 one or both sides, or in order to fulil the samefunction it may be made of any crosssection other than circular, andinstead of employing nuts at both ends of the pin a solid head may beformed at one end. 9o

Instead of employing outside washers b, the nuts or heads upon the endsof the drawingup pin may fulfil the duty of both drawing up andclamping.

In Figs. 6, 7, and S the outside washers are dispensed with and the nutsor heads of the bolt are made to take the place of the outside washersand are sufficiently large to embrace the sides of the vframe, while theinterposed or inside washers are made stationary or fast 10o with theframe by having keep channels formed within their outer faces and holdthe saine function as the keep-grooves in the intermediate Washerspreviously described.

d is a nearly-all'round clip, with the terminal and free ends fr?,formed with lugs fr", having all-through holes d4 through them, and withits outside facings a being prefer ably of soft metal.

f are interposed or inside washers, each having a keep-channel f, Withinwhich the sides e of the double-sided frame lie7 and also having a roundholcf2 through its middle for taking onto the outer part c2 ofascrew-ended square spindle c, and teeth or serrations f4 upon its innerface, which teeth run, preferably, at right angles to the direction ofthe keep-channels and embed themselves into the soft metal of the facesof of the clip on the screwing up of the nuts d, one of which may beiixed and form a head to the pin.

Having fully described my inve11tion,\vhat I desire to claim and secureby Letters Patent isl. In a cycle-saddle-seeu ring attachment or boss,the combination of the spring-clip c provided on the adjacent inneriaeesof its ends with lugs as, the pin or bolt c iitted in sockets or holesu," formed in the ends of said clip, Washers f arranged on the ends ofthe pin in juxtaposition to the sides of the clip, outer washers barranged on said pin outside the washersf, registering grooves formed onthe adjacent faces of said washers, and nuts for clamping the Washersand the ends of the clip on said pin, substantially as described.

2. In cycle-saddle-seeuringattachments or bosses, the combination andarrangement of the springclip ,With the pin or bolt c, iitting into thesockets or holes a4, the Washersj", the outer Washers b, the fralincsides e, and the nuts d, all substantially as and for the purposesdescribed and set forth.

In a cycle-saddleseeurin g attachment or boss7 the combination of thespring-clip a, the pin orbolt e fitted in sockets or holes a formed inthe ends of the clipvashers f arranged on the ends of the pin andprovided on theirinner faces with teeth adapted to engage the outerfaces of the clip and provided on their outer faces with keep-groovesfor the reception ot the frame sides, frame sides c 'seated in saidkeep-grooves, and nuts arranged on the threaded ends of the pin,substantially as described and for the purpose specified.

In testimony whereof I have hereunto set my hand in presence olf twosubscribing witnesses.
